To all wlw/nt t 'may concern:

Be it known that` LINos- B. TANNER, citizen` of the UnitedStates, residing at; Chicago, in the county: of: Cool;` and State Y of Illinois, vhave invented :a certain newr and useful Improvement-in -Liquid-'l`rea.ting

Apparatus, ofwhich the4 following. isa full, clear, concise,- and? exact z description.

My invention relates to liquid` treating apparatus andf-inits preferredembodiment is an improvement upon `the liquid treating apparatus disclosed im myi United: States Patent.1,407`,499, dated February 2li, 1922. The apparatus of that.' patent ineludeda settlingl ehamberfa: chemical tank, a source of liquid under pressure,` a piperthrougli which` `the liquid passes into the settling chamber for treatment," a-chemical pipe-` also dischargingintotiret-settlingv olian'iber. and

having a; port; in its side.: throughcwhich ehemicalfpas'ses from-the chemical `tank into the pipe, a valve Within the liquid pipe and controlling ports in saidpipe and rising and `falling `according to the pressure ofthe liquid, and Vmechanism.y Agoverned by said valvefand governing?theheight of` the chemil cal zpipe, `whereby the i varying volumes `of Water and.cliemicaliwill'be. in liXedf'pro; portioni to w secure` the yrequiredr.r reaction* `loetween" the chemical' and the `materia-ls that are?tobepreeipitated out of= `the. liquid. later may readily be sftenedby'means of suchvanequipinent having `t-he character# isticsiof.thelinvention` The mechanism .com

suoli a nature that morethanone chemical discharge pipe or other valve may1be1controlled `by a single valve `in the Aliquid i' pipe softha-t a .pluralityfof differing chemicals may be admitted to the liquid Where `Such are requiredtotreat the liquid.'

The tank l is of any1 suitable formation and is provided Witha central` Settling chamber'2, which may be in: the fornrofa-stand pipe.` This chamberjhas no k"communican tionv with `the `tanlr space* surrounding it, ex*- cept at theV bottom, in aocordanoewith Well known practice. V Thewifaterto be treated is: suppliedfrom the city` `mains yor from any other suitable source andl flows through the riser 31 that may-pass upvvardly through/the settling eha1nber2 tolthe placefwhere the raw Water is to be discharged into such chamber. This chamber is provi'dediwith a oontinuationj in the formof "a funnel`4'at the upper endof the chamber. 1 n Y As Will be more fully hereinafterV set forth, the `Water passing fromthei pipe 3 into the settling chamber-2controlsthe How of `chemical from the: chemical tanks 5f, .5 into the funnel 4iso that thechemi'cal'will fiow in quantities proportional to the amount of raw Water diselrarged into said funnel'. The mixture of Water alidchemi'cal is initiatedin the funnel andTis-promotedby the.

upright perforated interleavedf baffle ffplates G, 7 carriedby the, horizontal imperforate passa-ge Walls 8, Qiand-tlieE horiontal'fper forated balile plates-10,V 11. i The baffle-plates form `a part ofV the `subject matter of my copending `applica-tion`` Serial No. 487,121', filed July23, 1921. i

The chemicals are supplied to ther cheinii cal l tanks from separata chemical supply supply pipe 13, 13 is desirably continued nearly to the bottom of its corresponding chemical tank 5 or 5 and is there provided With a horizontal outlet slot opening 132 through which the chemical is distributed in sheets initially in a. horizontal direction. Each chemical tank has aA flaring side, as indicated at 133 in F ig. 2, so that the sheet of chemical coming into the tank is given a reverse motion, the inlet end of the pipe being at the side of the chemical tank opposite thearing 133. The discharge pipes leading from the chemical tanks are desirably also arranged as illustrated in Fig. 2 Where the discharge pipe 14 is shown as terminating nea-r the top of the tank 5. The level of the chemical in the chemical tank is deiined by the position of the upper end of the pipe 14 and is maintained at this level as long as the corresponding` pump (15) is in operation, such pump serving to maintain the flow of chemical into the cor responding chemical tank in sufficient yvolume to be in excess of that required so that the level of the chemical in the corresponding chemical tanks 5, 5 is maintained constant.

The upper end of pipe 3 is provided with Weir ports 16 that are elongated lengthwise of the pipe. A Weighted valve 17 has a range of movement extending through the zone of said ports and slightly on either side thereof, the valve functioning to completely close said pipe and to fully open said ports or partially open the same, depending upon the head or pressure of the water flowing upwardly in said pipe. Valve 17 has an upwardly extending stem 18. This stem is formed with as many uprightracks 19, 19 as there are chemical tanks 5, 5', each ack being individual to a tank. Pinions 20, 20 are rsepectively in mesh ivithsaid racks. Other upright racks 21, 21 are respectively in mesh with said pinions. The lower ends of the latter racks are joined by a horizontal cross piece 22, and their upper ends by a horizontal cross piece 23. This latter cross piece is extended at bot-h ends and carries pins 24, 24 that carry upright pipes 25, 25. The pinions cause the racks 21, 21 and the pip-es 25, 25 to move oppositely to the valve 17 and the racks 19, 19. Pipes 25, 25 pass through and are in sliding relation to the bottom oi thecorresponding chemical tanks 5, 5', there being stutling boxes 26, 2G in said tank bottoms through Which the pipes 2r 25" may slide. These pipes discharge the chemicals into the tunnel 4. These pipes 25, 25 have ports 27, 27 in the region of the upper levels of the chemicals in the tanks 5, 5. The pressure exerted by the Weighted valve 17 upon the Water in the pipe 3 counteracts the proff sure ot this Water upon the valve su'tliciently to enable the valve to control the position of the pipes 25, 25 and their ports 27, 27. The arrangement and operation of these parts is such that When the bottom of the valve 17 is at the bottom oic the ports 16 that the bottoms ot' the ports 27, 27 are above the chemical in the tanks 5, 5. W' hen the bottom oit' said `valve is above the bottoms ofthe ports 16 the bottoms of the ports 27, 27 are'below the upper levels of the chemicals. The ports are so proportioned and interrelated that the amount ol water passing through the ports 16 and the amounts of chemicals tloiving through ports 27, 27 into pipes 25, 25 and through said pipes into the -funnel 4 are in fixed proportion, the volumes of chemicals flowing through the pipes increasing or decreasing With any increase or decrease of the tlow of Water. The Water and chemical in varying volume but in fixed proportion, are initially received in the funnel 4 from which they are passed to the channel containing the battles 6, and 7 and 'from this channel through the perforated battles 10, 11. as hitherto fully described.

lVhile tivo chemical tanks and attendant equipment are shoivn, it is obvious the number .maybe increased or reduced..

`While I 'have herein shown and particularly described the preferred embodiment ot my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made Without departing from the spirit ot my invention, but having thus described my invention l claim as nen7 and desire to secure by Letters Patent the following Liquid treating apparatus including a source of liquid furnishing liquid to be treated un-der pressure; a pipe communicating ivith said source; a valve in said pipe operated by the liquid, the pipe having a. port closed by said valve and also opened to varying extents bythe valve according to the pressure exerted upon the valve by the liquid; a settling chamber into which the liquid to be treated is discharged through said port; a chemical tank; a. chemical pipe movable up and down and having a port at one end near the level of the chemical in the chemical tank and communicating with the chemical tank to receive chemical therethrough, said chemical pipe discharging at its other end into the settling chamllO Aber; an upright rack coupled With Said l Valve; an upright raekeconnectecl with sai-cl chemical pipe; and gearing in mesh with saidreoks and Serving to move said chemical pipe oppositely to the valve whereby the extent of the port in the chemical pipe through Which Chemical ina-y flow is increased as said Valve increases the extent of the liquid port through which liquid to be Vtreated may flow and Vice versa.
